The Problem
Thomson Reuters Checkpoint and CCH IntelliConnect charge thousands per seat for clunky web portals. Meanwhile, your AI assistant has no access to authoritative tax sources. It guesses, hallucinates citations, and can't tell you where it found the answer.
Legacy platforms charge enterprise prices for basic search. Small firms and solo practitioners get priced out of professional-grade research.
ChatGPT and Claude are great at reasoning about tax law, but without access to real authorities, they fabricate section numbers and cite regulations that don't exist.
Consumer tax tools use outdated information with no citations. When you're advising a client, you need authoritative, up-to-date sources you can verify.
How It Works
Connect taxmcp.io to your AI assistant, then ask tax questions the way you normally would. Every answer comes back with real citations.
Add taxmcp.io to Claude Desktop, ChatGPT, or your preferred AI tool. One URL, under two minutes, and you're researching.
Ask tax questions in plain English. “What are the QBI deduction requirements?” “Show me §199A.” Your AI searches the actual IRC, regs, and rulings.
Every answer includes the exact section number, source URL, and cross-references. Real citations you can verify and share with clients.
Features
Ask questions the way you think about them. “Can my client deduct home office expenses?” returns the exact IRC sections, regs, and rulings that answer it.
Every result cites the exact section number with a link back to the official government source. No hallucinated references. No ambiguity. Citations you can put in a memo.
See how sections connect. When you look up §199A, instantly find every regulation, ruling, and related code section that references it, and everything it references.
Internal Revenue Code, Treasury Regulations, 24+ IRS Publications, Revenue Rulings from 2003–present, and IRS Notices; all searchable from one place.
Our system checks official government sources weekly for changes. You always get the latest version of the law, not last year's snapshot.
